SPECIFICATION forming part of Letters Patent No. 382,842, dated May 15, 1888.

Application filed November 28, 1887. Serial No. 256,298. (No model.)

To all whom it may concern.-

Be it known that I, JOHN F. STEWARD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain -Binders, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming part thereof.

Figure 1 is an outer side elevation of a binder-frame, showing a portion of my invention above the deck. Fig.2 is a detail front elevation of a part of a binder-frame, showing thesamc part ofrny invention which appears in planin Fig. 1. Fig. 3 is a detail plan ofapart of the upper arm of a binder-frame and certain Fig. 5 is a front elevation of a binderframe,

showing part of my invention which is located below the deck. Figs. 6 and 7 are perspectives, respectively, of two brackets,which have mated v halves of a journal-box for the packer-shaft,

and certain other bearings pertaining to my invention. Fig. Sis a perspective of the portions of the frame and brackets secured thereto underneath the deck.

The general purpose of this invention is to diminish the amount of frame-work which is necessary to support the various parts of a binder-frame. It comprises two parts-the devices which support the breast-plate and knotter-frame and devices which support the packershaft and other parts-below the deck.

A represents a main bar of the harvesterframe.

Bis the binder'gear standard, having the usual overhanging arms, 13 and B", and with them constituting the principal part of the binder-frame.

A represents a bracket or post which is supported on the main frame, and in turn supports the rear end of the binder-frame.

A is a bracket secured to the bar A and extending upward, leaning somewhat outward, and having at the upper end a bearing for the forward end of the needle rock-shaft,which is journaled, as usual, in the lower arm, B, of

the binder-frame.

D is the deck.

E is the trip rock-shaft.

F is the needle rock-shaft.

F is the needle.

G is the packer crank-shaft.

G G are the packers. p

G2 G are the packer guide-links.

H H is'a compound bracket, made up of two simple brackets, which have, respective ly, the upper and lower halves of a journalbearing for the packer-shaft. The: bracket H is secured by means of the wing or seat H to the under side of the arm 18 of the binder-frame. This bracket also has formed integral with it the tucker-cam H, of familiar form and function. The half of the packershaftjournal-box H, which is formed on the bracket H, opens upward and supports the packer shaft. This bracket also supports the bracket H in part, the half H of the packer journal box which pertains to the bracket H lying upon and being bolted fast to the half H. The bracket H has the bearing H, which receives the needle rock-shaft F, which further supports said bracket. The bracket H has a bearing, H, for the trip rock-shaft E, and the bracket H has in line with the bearing H and with the tripshaft E the eye H, which receives the pivot of the link G connected with the forward packer. The corresponding link G connected with the rear packer, is pivoted on the trip rock-shaft E.

Upon consideration of this structure it will be noticed that the needle rock-shaft F, being journaled in the arm 13 of the binder-frame and having a journal-bearing at the forward end in the post or bracket A which is sup ported directly on the main frame, affords support for the forward end ,of the binderframe and dispenses with any other support at that end. Next, that the bracket H being secured rigidly to the same lower arm, B of the binder-frame, afiords positive support for the packershaft and dispenses with the necessity for any other bearing for. that shaft forward of the bindergear standard. Also, that the bracket H, having the eye-bearing H through which the needle rock-shaft passes, gains support from said shaft, and, being bolted fast to the bracket H further assists the support of that bracket, so that the needle rockshaft is made the medium of transmitting the support afforded by the bracket or post A to ICO the packer-shaft. Also, that the packer-links are pivoted in line with the trip rock-shaft, and that shaft is utilized as the pivot of one of them. Also, that the brackets II and H being rigidly secured together, are, in effect, as described, a single compound bracket, which is supported by connection with the lower arm of the binder-frame and with the needle rockshaft.

Above the deck the k notter-frame K, breastplate L, and grain-check springs M M M requiresupport. 'Iheknotter-frameisprovided, as usual, with a sleeve, K, by means of which it is hung upon the binder-shaft O. The breast-plate is secured to the knotter-frame, as usual. The bar N, called hereinafter the check-spring bar, is secured to the inner end of the breast-plate, and the grain-check springs M M M are secured to and coiled around it. Heretofore it has been customary to support this bar at the rear end or at the forward end, and sometimes at both ends, upon the binder-gear standard or other support, reach ing down by some means to the basesupport of the binder-frame. I aim to dispense wholly with such end support and provide it sufficient support at or near the middle to uphold the inner end of the breast-plate and keep the knotter-frame in proper position, and also to hold the check-springs. For this purpose I form said bar N only long enough to cnableit to hold the check springs in their proper places with respect to the height of the grain, and while the end portions are preferably rounded, as illustrated, to facilitate the action and reaction of the springs coiled about them, I prefer to leave the intermediate portion square, oratleastpolygonal, to facilitate securing toit the braces]? P, which are each secured at one end into one of the lugs 13 which project from the arm B of the binder-frame, one projecting upward and the other downward, so that the points at which said braces P P are secured are several inches apart. Said braces extend inwardly above the deck, approaching each other in a vertical plane, and are both united to the bar N, being,preferably,also secured to each other by the same bolts which unite them to said bar, and to give them very firm attachment to said bar they are flattened at their inward portion, though preferably round throughout their remaining extent, and such flattened portion is bent at right angles to the remainder and forms afoot,to which the bar N is secured. The distance by which the ends of said braces are separated at the binder-frame arm B renders them, when thus joined at their inner endsas a bracket, very stiff in a vertical plane, and such plane (the plane in which they extend from the arm B to said bar N) being about midway in the length of the bar, or midway between the foremost and rearmost pressure exerted by the grain to distort or move the barN and the breast-plate, the knotter-frame is in the best position to resist such strain and pressure. In order to enable it to resist pressure in horizontal direction also, the brace R is provided, which is also secured to the bar N by a fiat foot, R, which is secured to the bar, preferably, by the same bolts which fasten one or both of the braces I, the rear end of said brace B being bolted fast to the arm B of the binder-frame well toward the rear, near the gear-standard B. These three braces, formed, as described,

- with bread or extended fastenings to the bar N and bracing each other, as the legs of atripod,give the bar N rigid fixedness of position, and being thus securelyjoined to it near its middle render any end supports for it needless.

It will be obvious that the braces may be connected to the breast-plate without the intervention of the bar N, and in the structure shown they should be considered as in reality connected to the breast-plate to uphold it, the said bar N being a convenient medium of connection,being necessarily located in the vicinity and itself rigidly braced to hold the graincheck springs M M M.
